Some of the routines in ACPI driver/acpi/tables.c can be shared with
parsing CDAT. CDAT is a device-provided data structure that is formatted
similar to a platform provided ACPI table. CDAT is used by CXL and can
exist on platforms that do not use ACPI. Split out the common routine
from ACPI to accommodate platforms that do not support ACPI and move that
to /lib. The common routines can be built outside of ACPI if
FIRMWARE_TABLES is selected.

When MADT is parsed, print RINTC information as below:

ACPI: RISC-V INTC (acpi_uid[0x0000] hart_id[0x0] enabled)
ACPI: RISC-V INTC (acpi_uid[0x0001] hart_id[0x1] enabled)
...
ACPI: RISC-V INTC (acpi_uid[0x000f] hart_id[0xf] enabled)

This debug information will be very helpful during bring up.

Paul reports that the ACPI core complains on every boot about a missing
CEDT table. Unlike the standard NUMA tables (SRAT, MADT, and SLIT) that
are critical to NUMA init, CEDT is only expected on CXL platforms. Given
the notice is not actionable lower its severity to debug.
